Bitx40 cal switch
WebJan 25, 2024 · Wire the top of the 10k pot to TX 12v, the bottom of the 50 ohm resistor to ground. Run a wire from the junction between the 1k and 50 ohm resistors to one terminal of a straight key. Run a wire from the other terminal of the straight key to the top of C107 near the balanced modulator. WebA switch between R15 and R16 will act like a 20 dB attenuator. Or insert a 10 K variable resistor there for continuous control from zero to 17 dB. ----- The mod that made the biggest improvement for me was an RF Gain knob. I added a 10k ohm variable resistor (potentiometer) in series with R16, so I now have an RF Gain control on my radio.
